SAFETY EMERGENCY ATTACHMENT non .WHEELS Appiiation mea April 3, 1925. serial No. 20,3154;H

rlhis invention, stated in its broadest terms, relates to a safety emergency attachment for automobile Wheels and has more especial relation to the type of attachment shown, de-

scribed, and claimed in Patent No. 1,404,802,

granted to J. P. Spicer, under date ot January 31, 1922.

The leading object of the present invention may be said to reside in the provision ot a device of the character stated adapted for attachment to motor vehicle Wheels, and especially designed for use upon roads or highways composed chiefly of dirt Which trequently become soft and muddy so that proper traction or" automobile Wheels cannot be maintained.

Other and furthe'robjects of the present invention reside in the provision of general details ot construction and arrangement and combination of parts for attaining the results sought by the leading object. y

Other and still further objects not at this time more particularly referred to Will appear hereinafter.

The invention consists of the novel construction hereinafter described and nally claimed.

The nature, characteristic features and scope of the invention Will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, and in Which:

Fig. 1,is a View in side elevation of a motor vehicle wheel equipped With a device embodying the invention.

Fig. 2, is a fragmentary View drawn on an enlarged scale, illustrating details of construction in Fig. 1.

Fig. 3, is a View in cross section taken upon the line 3-3 of Fig. 2.

Fig. 4, is a view in section taken upon the line 4 4 ot Fig. 1.

Fig. 5, is a detail viewot the spring pressed pin shown in Fig. 4.

Fig. 6, is a detached vieW- of 4the screw threaded ring shown at the lower portion ot.

Fig. 4.

Fig. 7, is a detail view of the sleeve shown at the upper portion of Fig. 4; and

Fig. 8, is a detail view/*of the sleeve shown at the right hand side side of Fig. 3.r

For the purpose of illustrating my invention have shown in the accompanying drawings one form thereof which is at present rrr-Ca if preferred byrme, since the same has been found in practice to give satisfactory and reliable results, although it is toV be'understood that the various instrumentalities*of which my invention consists can be variously arranged and organized Without departing from the spirit or scope of my invention.

f Referring now to the drawings in detaih the reference numeral 1 designatesithe hub of any desired form otfmotor vehicle, 2 the spokes, and 3 the fellythe'reof. Carried by the telly 3 is a rim 4 to accommodate a def tachable tire v5 of any desired or1n."Detach ably liXed `with respect to the telly 3 as `by means of a plurality of bolts Gis an annular casting 7 arranged inf concentric relation vvith respect to the tire 5 and in spaced relation therefrom. IThe annularcasting 7 is' provided With a plurality of lugs 8 apertured for bolt reception. The apertures of the lugs 8 are a tritle largerithan the diameter of the bolts 6 so that taperedsleeves 9, seev Fig. 8',

vmay be fitted around the bolts 6 and'be passed through theapertures of the casting 7. Thus, When the nuts 10 are tightened the casting 7 may be positively clampedwith respect to telly 3.A The casting 7 isrigidly provided With a plurality ot cylindrical casings l1, see

Fig. 4, internally screw-threaded toireceiv'e the screiv threaded sleeves 12, shown in Fig. 6. Within each cylinder 11 is arranged a spring pressed rod 13 having a pointed endl 14, see Fig. 5, eachof which rods 13 is provided with a shoulder l5 for abutting against the inner side of a sleeve 16 ittedto the outer end of each cylinder 11. The sleeves 16 are best seen in Fig. 7. Thus, with a rod positioned Within a cylinder 11, proper adjustment of sleeves 12 would provide proper tension'upon the spring pressed rods 13 asis readily apparent. In order to maintain the sleeyes 12 in proper position when adjusted, use 1s made of pins 17, see Fig. 4. Thesepins 17 are accommodated by the slotted portions 18 of oasings 11.y From the above described eov loo

construction of parts it is apparent that as a vehicle Wheel moves over the ground the rods 13 move in a direction toward the hub of the vehicle Wheel because of the springs 19. Ob- 5 viously, ifit be a soft, muddy road the rods 18 will dig into the soft, muddy substance and thus providerproper traction mediums as is readily apparent. The pins 17 serve as set screws to prevent the rotation-and Working Y loe of the' sleeve 12 Which is threaded to the end of the casing 11, said pins 17' engaging` the aligning slots in thel ends of said casings and in said threaded sleeves 12. l

It Will now be apparent that I have devised a novel and useful construction which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description and While l have in the present instance shown and de- 20 scribed the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, itis to be understood that thesame isA susceptible of moditcation in variousL particulars Without departing from the spirit 0r scope of the in vention or sacrificing any of its advantages.

Having, thus described my invention, what l` claim as new and desire to secure by Letters Patent, is: t An attachment for Wheels comprising` an annular member having a plainexterior surface and being of channel cross section, the open side of said annular member facing said Wheel, andf plurality of cylindrical Vcasings y formed integral with and concealed from View by said annular member, each' of said cylindrical casings having at its; outer end a flanged opening, a flanged bushing fitting in saidr opening, a spring4 pressed pinthaving o its outerend pointed and having, a shoulder intermediate its ends abutting against said bush-ing, the inner portion of' said pin being o disposed Withinsaid casing,v a vertically slotted sleeve threaded into the other end of said 45, casing and adapted' to maintain said pin in position, and fastening devices common to said casing andv said sleeve.` Y

In testimony whereof, I have hereunto signed my name.
